A composition (A) comprises surface-active detergent and a cationic vinyl lactam copolymer, an acrylic terpolymer (I) derived from: (a) 1-6C alkyl (meth)acrylate; (b) a vinyl heterocyclic compound, (meth)acrylamide or mono- or dialkylaminoalkyl (meth)acrylate or (meth)acrylamide; and (c) one of a wide range of further monomers, such as surface-active esters, ureas or urethanes. A composition (A) for washing keratin fibers, comprises cosmetic medium containing at least one surface-active detergent and at least one cationic vinyl lactam copolymer (CVLP) (containing at least one of methyl-vinyl-imidazolium salt, polyurethane, methacrylamidopropyl dimethylamine, methacrylamidopropyl trimethylammonium or vinyl-caprolactam units). Additionally the composition comprises at least one acrylic terpolymer (I) comprising: (a) 5-80 (preferably 15-70, especially 40-70) wt.% units derived from a 1-6C alkyl (meth)acrylate; (b) 5-80 (preferably 10-70, especially 40-70) wt.% units derived from a vinyl heterocyclic compound (containing at least one O or S), a (meth)acrylamide, a mono- or di-(1-4C alkyl)-amino-(1-4C) alkyl (meth)acrylate or a mono- or di-(1-4C alkyl)-amino-(1-4C) alkyl (meth)acrylamide; and (c) 0.1-30 (preferably 0.1-10) wt.% units derived from: (i) a urethane obtained by reacting a mono-ethylenically unsaturated isocyanate with a 1-4C alkoxy-terminated nonionic surfactant, (ii) a 1,2-butylene oxide/ethylene oxide block copolymer, (iii) a surface-active ethylenically unsaturated comonomer obtained by condensing a nonionic surfactant with an alpha , beta -ethylenically unsaturated carboxylic acid or its anhydride, (iv) a urea-type surface active monomer obtained by reacting a mono-ethylenically unsaturated monoisocyanate with a nonionic surfactant having an amine function, or (v) a (meth)allyl ether of formula CH=C(R1)CH2-O-AmBnApR2 (II) or (vi) a urethane-type nonionic monomer obtained by reacting a monohydric nonionic surfactant with a monoethylenically unsaturated isocyanate. R1 = H or Me; A = propyleneoxy or butyleneoxy group; B = ethyleneoxy; n = 0-200; m, p = 0 or integer less than n; R2 = hydrophobic group of at least 8C.
